Additional information: d9, g3, h3, h6.The complaint allegation regarding the trigger being locked was confirmed.However, no broken components were observed on the returned device, and no evidence of the reported broken pieces was received.One unpackaged ar-4501 1meniscal cinch¿ ii, batch 15374692, was received for evaluation.The device arrived for evaluation without the anchor, suture, and depth stop.Evaluation of the returned device found that the right trigger was locked in place on the handle and could not be moved.The secondary trigger button was noted not to lock in the rear position and could be freely actuated.Evaluation of the shaft and internal deployment mechanism identified no damage or breakage.The most likely cause of the reported failure is a use error, including improper surgical technique associated with the device.According to the surgical technique.Meniscal cinch¿ ii technique.4a.Advance the button completely to deploy the first implant.4b.Retract the button until it locks in place flush with the adjacent button.5.Advance the second implant into the needle tip by pushing the second button forward to the raised indicator.Note: rotating the needle slot away from the first implant and penetrating the meniscus can sever the suture.6a.Advance the needle through the meniscus by pushing the entire handpiece forward until the desired depth is reached.Advance the button past the indicator to the endpoint to deploy the second implant.6b.Retract the button until it locks in place flush with the adjacent button.Dfu-0156-eo revision 1 - suture retention devices g.Precautions 4.Particular attention should be paid to excessive manually applied forces when deploying the device to avoid over-deployment.6.Excessive movement of the device between deploying implant #1 and implant #2 can disrupt the deployment mechanism.7.In the event of unsuccessful implantation, the device(s) should only be retrieved under visual confirmation and if loose.Any attempt at retrieving devices entrapped in tissue or without visual confirmation of location may result in tissue damage or injury to the patient.8.Meniscal cinch ii and softstitch devices only: do not advance the implant beyond the tip of the cannula before penetrating the meniscus.Meniscal cinch device only: do not pull the trocar back into the cannula after it has been advanced as this could prematurely deploy the implant.10.Meniscal cinch device only: if resistance is felt during implant deployment, advance trocar to depth stop and rotate trocars back and forth with controlled pressure.This is to avoid damaging implants.11.Meniscal cinch device only: to avoid premature tension to construct do not pull external suture before releasing trocar #2.
